Abstract: UNLABELLED: Subclavian steal syndrome (SSS) involves changes in hemodynamics secondary to proximal subclavian artery stenosis and/or occlusion where the subclavian artery "drains" the blood from the vertebral artery. It sometimes induces neuromuscular symptoms, especially in cases with bilateral involvement. We report the case of a 65-year-old symptomatic male with severe bilateral SSS with complete vertebral reversal. Doppler ultrasonography yielded inconclusive results because of a scar in the left lower neck region leading to poor acoustic windows. Subsequent magnetic resonance imaging with contrast-enhanced magnetic resonance angiography and velocity-encoded phase-contrast magnetic resonance imaging provided the vascular morphology and blood flow pattern which allowed subsequent interventions to be successfully performed. KEY WORDS: Angioplasty; Phase-contrast magnetic resonance imaging; Subclavian steal syndrome.
